Specification of Letters Patent.

Patented Oct. 27, 1908.

a aauon filed March 25, 1903. Serial No. 423,197.

To all whom it may concern:

Be it known that I, EDWIN M. BROWN, a citizen. of the United States,residing at Ashtabula, in the county of Ashtabula and State of Ohio,have invented certain new and useful Improvements in and exactdescription of the invention, such as will enable others'skilled in theartto which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the-letters and figures ofreference marked thereon, which form a part of this specification. Thisinvention relates to new and useful improvements in trap-nests andconsistsof means whereby a hen raise a pivotal trap which looks whenfalling by gravity.

The invention comprises various details of construction, combinationsand arrange ments of parts which will be hereinafter fully described andthen specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which:-

Figure 1 is an elevation showing the trap set in readiness to be raisedbya hen. Fi

'2is a similar view showing the trap at its lowest limit and locked.

Reference now being had to the details of drawings by letter, Adesignates the board of a nest and has an opening B therein. C is a doorpivotally mounted upon a pivot D u on the board, and E is a stop uponthe card to limit the downward throw of said door.- The forward freeedge of the door has a notch F formed therein, and G- is a pivot pinmounted upon the board upon which pin a gravity pawl H is pivotallymounted. It will be noted that said pawl H is mounted at one side of itscenter and so arranged that, when tilted, the weighted end thereof willfall down and engage the notch locked I In operation, the locking awlisarranged as shown-in Fig. 1 of the rawings so that the hen by puttingits head through Trap-Nests .and I do hereby declare the following to be-a full, "lear,

may automatically automatically F and hold the door opening beneath thedoor and pushing up lightly upon the door will cause thepawl to; tiltand its weighted end will fall to the position shown in Fig. 2 of thedrawings and engage the notch F when the door falls by gravity againstthe stop E, thereby locking the door at its lowest throw. To set thedoor, the pawl to the position in readiness to of the door.

In Fig. 2 of the drawings, I have shown dotted lines the opening so thatthe device may be utilized as an open nest. In said dotted lines, oneend of the pawl is shown as engaging a recess formed in the'end of thedoor.

From the foregoing, it will be noted that, by the provision'of a doorfor nests as shown and described, a simple and eificient means isafforded which will allow "a hen to raise the door and pass through theopening, the door automatically looking as it falls by gravity.

' What I claim to be new is In combination with an apertured board, atrap door pivoted a short distance from the marginal edge of'the openingin said board, a stop upon the latter to limit the downward throw of thedoor, the upper portion of the swinging end of the latter provided witha shoulder, a pawl pivotally mounted at one side of its center upon saidboard and having two operative ends, one being heavier than the other,the heavier end of the pawl adapted to engage said shoulder to hold thedoor upon said stop, said pawl being so mounted with respect to the doorthat the is swung about upon its pivot shown in solid lines in Fig. 1 beagain tilted by the raising heavier end of the pawl will hold itsopposite end against the set, as set forth.

In testimony whereof I hereunto affix my ignature in the presence of twowitnesses.
